【 摘 要 】

The α- and β-apoproteins from the B800-850-complex of Rhodopseudomonas sphaeroides strain 2.4.1 have been sequenced. These results have been compared with those previously obtained with the analogous antenna apoproteins from the carotenoidless mutant R26.1 [9]. The α-apoproteins differ at position 24, where a valine residue present in the wild-type sequence is replaced by a phenylalanine residue in the mutant. The α-apoproteins differ at the N-terminus. In the wild-type β-apoprotein some chains have methionine at the N-terminus and some have an N-terminal threonine, while in the mutant the N-terminus is threonine.
